Working in Grimsby
In Grimsby we cover DN31, DN32 and DN34; we also cover Cleethorpes, 1.8 miles away, and Louth.
Grimsby has a wide mix of house ages, so the survey is where we spot old lead pipework, weak joists or a tight soil stack. If your Grimsby loft conversion has a bedroom but no bathroom, the survey starts with where the soil stack runs and how much headroom you have. If your Grimsby loft shower is weak or the waste drains slowly, the fix is often in the pump or the pipe fall rather than the shower itself.
Supplies across most of Lincolnshire are hard. If your supply in Grimsby is the same, limescale on shower glass and heads is a real issue: easy-clean glass, rub-clean nozzles and a squeegee make a big difference. Hardness varies street by street, so check the figure for your postcode with your water supplier.
What the job includes
- A check of your hot-water system and of the pressure and flow you actually get at loft level
- Electrics by a qualified electrician, tested and certified, then tiling, testing and handover
- A shower pump on a gravity system, an electric shower, or advice on moving to mains pressure, depending on your system
- A survey of the headroom across the room, with the usable height marked at each fitting position
Decisions to make first
Bath or no bath
A bath under the slope makes good use of low space, but the floor has to carry it when it is full of water and someone is in it.
Where the shower goes
Under the ridge or in a dormer, where the full height is. A walk-in shower with a single panel is usually easier to fit to a roof line than a framed enclosure.
Rules that apply in England
In England, new drainage and a new connection to the soil stack fall under Part H, a new bathroom needs extract of 15 litres per second intermittent or 8 litres per second continuous under Approved Document F, and new circuits are notifiable under Part P. If the work includes an unvented hot-water cylinder, it must be fitted by a G3-qualified installer.
